Research: Rice professor reports on the impact of personalized health care marketing

Amazon is famous for targeted marketing that approaches customers based on their unique needs. Like other successful businesses, such as Netflix, the company taps into machine learning, which uses customer data to understand their behavior.

Hospitals and medical centers rely on marketing too, investing heavily in direct-to-patient outreach to urge at-risk people to get regular screenings. Johns Hopkins Hospital's cancer center, for example, uses emails, letters, seminars and community events to encourage patients to get screened for potential cancer. The high cost of cancer treatment makes this effort worth it: research shows regular screenings help with early detection, leading to more cost-effective treatments and better prognoses.

But hospitals can – and must – improve their outcomes much more, by melding this essential outreach with individually tailored communications based on machine-learning insights.

In an award-winning paper, Rice Business Professor Vikas Mittal and colleagues developed new algorithms indicating that targeted, personalized outreach can increase screenings among at-risk patients. "Outreach marketing" – including sending informational letters and talking to patients about potential barriers to screening – was indeed a powerful motivator for patients to get screened, ultimately lowering health care costs for patient and hospital. But patients with different characteristics, Mittal's team found, responded differently to marketing interventions. When it came to marketing campaigns for cancer screening prevention, one-size-fits-all outreach efforts were neither effective nor economical. Personalized marketing works better for preventing cancer.

To conduct their research, the researchers randomly divided 1,800 patients at UT Southwestern Medical System at risk for hepatocellular carcinoma – the most common type of primary liver cancer – into three groups – usual care, outreach alone, and patient navigation, which includes help such as follow-up calls, motivational messages and assistance spotting specific barriers. They followed each group to see if patients scheduled an MRI or CT scan within six months, from 6-12 months and from 12-18 months.

The first group was asked to receive a screening during their doctors' visits and wasn't contacted after that. The second group received a one-page letter in the mail, then staff called patients who didn't schedule a screening. The third group receiving patient navigation got the same treatment as the second group supplemented with phone calls designed to identify potential barriers, which they used to give customized motivational messages encourage coming in for a screening.

The researchers used patient data from medical records, including patients' age, gender, ethnicity, income, commute time, health status, how often they received healthcare services, whether or not they had insurance and how populated their neighborhoods were.

Following traditional methods, Mittal's team found that the patients who got a letter and call were 10-20% more likely to complete a screening, while those who got the customized motivational messages were 13-24% more likely to schedule their screening. But this is where traditional medical research stops, without asking a crucial question: Within each group, such as those of the 600 patients receiving patient navigation, could screening rates differ based on patients' individual characteristics?

In past research, everyone receiving the same stimulus is presumed to respond the same way. There was no statistical technique to separately estimate the responsiveness of patients with different characteristics. Mittal's team solved this problem by using a machine learning technique called causal forests.

By using "causal forests" to quantify how each of the three marketing approaches could be applied to different patients, Mittal's team found, improved returns on the traditional approach by a remarkable 74-96% – or by $1.6 million to $2 million.

Using traditional methods, physicians would have concluded that every patient should get patient navigation because it was a more intensive marketing approach. The causal forest method showed otherwise: there are small groups of patients with unique characteristics who respond best to specific types of overtures. Minority women in good health who had insurance, visited the doctor often and lived close to clinics in more populated neighborhoods responded especially well to all three types of outreach interventions. Younger patients with long commutes who live in neighborhoods with more public insurance coverage embraced the second type of intervention, outreach alone. And older patients in higher-income neighborhoods favored the patient-navigation approach.

The stakes for common marketing practices like "AB testing" could not be higher. In AB testing, marketers run randomized experiments such as showing ads to some people and not to others. If those seeing an ad, on average, buy more, the conclusion is to blanket the market with ads. But AB testing ignores the fundamental idea that customers exposed to an ad might buy differently in response to an ad based on their individual characteristics. In fact, research shows, many customers seeing a non-tailored ad will buy less than those not seeing an ad.

Personalized marketing can uncover these differences and substantially increase the return on marketing investments in many settings such as retail and ecommerce, services marketing, business-to-business marketing and brand management. Healthcare companies should consider dedicating more resources to machine learning, which can power data-driven patient-centric outreach programs. Because individual health is a civic good, policy makers and organizations need to support these personalized outreach programs.

As for patients themselves, giving detailed personal data to a doctor or receiving highly personalized, unsolicited phone calls legitimately can seem like an invasion of privacy. But Mittal's research shows, it measurably has the potential to save your life.

Houston-based Data Gumbo, an industrial blockchain-software-as-a-service company, announced that it has signed a contract with Equinor. The global energy company's venture arm, Equinor Ventures, supported the startup's $7.7 million series B round, which closed last year.

The company's technology features smart contract automation and execution, which reduces contract leakage, frees up working capital, enables real-time cash and financial management, and delivers provenance with unprecedented speed, accuracy, visibility and transparency, per the release.

“Equinor is an industry trailblazer, demonstrating the true value of our international smart contract network to improve and automate manual processes, and bring trust to all parties,” says Andrew Bruce, founder and CEO of Data Gumbo, in a news release. “Smart contracts are playing a critical role in driving the energy industry forward. Our work with Equinor clearly demonstrates the benefits that supermajors and their supply chain customers, partners and vendors experience by automating commercial transactions. We are proud to continue our work with Equinor to help them realize the savings, efficiencies and new levels of transparency available through our smart contract network.”

Equinor opted into a pilot with the company a few years ago.

“Since piloting Data Gumbo’s smart contracts for offshore drilling services in 2019, we have worked with the company to continually refine and improve use cases. We now have the potential to expand Data Gumbo’s smart contract network to enable transactional certainty across our portfolio from the Norwegian Continental Shelf to our Brazilian operated assets and beyond,” says Erik Kirkemo, senior vice president at Equinor. “GumboNet reduces inefficiencies and processing time around contract execution in complex supply chains, which is a problem in the broader industry, and we look forward to realizing the streamlined process and cost savings of its rapidly expanding smart contract network.”
